Abstract
Description
Die Erfindung betrifft eine Wasserarmatur mit einem am Ende eines Rohres befindlichen Zulauf und einem eine Zapfstelle bildenden Abfluss im Bereich des zweiten Ende des Rohres, mit einem Ventiloberteil, einem Belüftungsventil und einem Rückfluss-Sperrventil, das innerhalb des Rohres einen Ventilsitz und in Strömungsrichtung des Wassers dahinter einen mittels einer Spindel mit dem Ventiloberteil verbundenen Ventilteller aufweist, der in Längsrichtung der Spindelachse gegenüber der Spindel um ein vorgegebenes Maß beweglich gehalten und in Richtung auf den Ventilsitz mittels einer Feder vorgespannt ist.The invention relates to a water fitting with an inlet at the end of a pipe and a Drainage point in the area of the second end of the pipe, with an upper valve part, a ventilation valve and a non-return valve, a valve seat inside the tube and in the direction of flow the water behind you by means of a spindle with the valve top connected valve plate, which is in the longitudinal direction of the spindle axis across from the spindle is held movable in a direction and in the direction is biased to the valve seat by means of a spring.
Wasserarmaturen dieser Art sind bekannt. Sie werden überwiegend in frostgefährdete Außenwände von Gebäuden eingebaut, um außerhalb der Gebäude liegende Verbraucher zu versorgen. Bei derartigen Armaturen liegt der Ventilsitz im frostsicheren Innenbereich der Wände. Wird das Sperrventil geschlossen, läuft das Rohrstück zwischen Ventilsitz und Entnahmestelle aufgrund eines auf der Wand-Außenseite liegenden Belüftungsventils vollständig leer, sodass einem Frostschaden der Armatur sicher vorgebeugt wird. Da es sich in der Regel um Trinkwasserarmaturen handelt, muss sicher gestellt werden, dass kein Wasser aus dem Rohrabschnitt zwischen Ventilsitz und Entnahmestelle in die Wasserversorgung zurück laufen kann. Hierzu ist der Ventilteller an einem axial zum Rohr verlaufenden Stift befestigt, die in einer am freien Ende der Ventilspindel angeordneten Zentrierhülse geführt ist. Der Stift durchsetzt eine zwischen Hülse und Ventilteller angeordnete Schraubendruckfeder. Bei regulärer Entnahme drückt der Wasserdruck den Ventilteller gegen die Kraft der Feder in Richtung der Entnahmestelle und gibt das Sperrventil frei. Bei Umkehr der Fließrichtung des Wassers drückt die Feder den Ventilteller jedoch gegen seinen Sitz und verhindert so einen Rückfluss.Water fittings of this type are known. she are prevalent in frost endangered Outer walls of buildings built in to outside the building to supply lying consumers. With such fittings lies the valve seat in the frost-proof interior of the walls. Becomes the shut-off valve is closed the pipe section between valve seat and tapping point due to one on the outside of the wall horizontal ventilation valve Completely empty, so that frost damage to the valve is reliably prevented. Since it is usually about drinking water fittings, it must be safe be put that no water from the pipe section between Run the valve seat and tapping point back into the water supply can. For this purpose, the valve plate is on a pin running axially to the tube attached, which is arranged in a at the free end of the valve stem centering guided is. The pin passes through an arranged between the sleeve and valve plate Helical compression spring. With regular removal presses the water pressure points the valve disc against the force of the spring the tapping point and releases the shut-off valve. When reversing the flow direction of the water the spring, however, prevents the valve disc from seating such a backflow.
Bei dieser bislang verwendeten Bauform kann jedoch nicht vollständig sicher gestellt werden, dass die oben beschriebene Dichtwirkung im Rückflussfall auch tatsächlich eintritt, da der Ventilteller aufgrund des für die Funktion notwendigen Spiels in den Führung von Ventilteller und -spindel im ungünstigen Fall nicht zentrisch auf dem Sitz aufliegt, sodass die Federkraft nicht zum Dichten ausreicht. Zudem können sich Schmutzpartikel in die Führung der den Ventilteller haltenden Stift setzen, was zu einer Blockade führen kann. Aufgrund dieser Nachteile erfüllt die bislang verwendete Bauform beispielsweise nicht die strengen Anforderungen der Deutschen Vereinigung des Gas- und Wasserfachs e.V. an die Rückflusssicherheit.With this design used so far, can but not completely be ensured that the sealing effect described above in the event of reflux actually occurs because the valve disc is necessary for the function Game in the leadership In the worst case, valve disc and spindle are not centric rests on the seat so that the spring force is not sufficient for sealing. You can also dirt particles in the guide of the pin holding the valve disc in place, causing a blockage to lead can. Because of these disadvantages, the previously used meets Design, for example, does not meet the strict requirements of the Germans Association of the gas and water specialist e.V.
Ziel der Erfindung ist daher, die Rückflusssicherheit bei hoher Lebensdauer des Ventils wesentlich zu verbessern, ohne dass hierzu eine aufwendige Konstruktion notwendig ist. Bei einer Wasserarmatur der oben genannten Art besteht die erfindungsgemäße Lösung darin, dass der Ventilteller einen Dorn aufweist, der zentrisch von der druckseitigen Ventiloberfläche absteht und zusammen mit einer auf der Druckseite des Ventils angeordneten Abstützung eine Führung für den Ventilteller bildet.The aim of the invention is therefore that Backflow safety with a long service life of the valve to improve significantly without that a complex construction is necessary for this. At a Water fitting of the type mentioned above, the solution according to the invention consists in that the valve plate has a mandrel that is centric from the pressure side valve surface protrudes and is arranged together with one on the pressure side of the valve support a tour for the Valve plate forms.
Diese Konstruktion bietet entscheidende Vorteile. So bleibt das erwünschte Spiel zwischen Zentrierhülse und des den Ventilsteller haltenden Stiftes erhalten, sodass die Leichtläufigkeit der Anordnung gewahrt bleibt. Das Spiel kann auch so groß gewählt werden, dass Verunreinigungen die Funktionalität der Armatur nicht gefährden. Eine Quelle derartiger Verunreinigungen sind Kalkablagerungen, die entstehen, wenn die Armatur häufig wechselnd trocken und nass ist. Durch die zweite Führung kann eine sichere Positionierung der Dichtscheibe vor dem Ventilsitz erreicht werden. Die auf der Druckseite des Sperrventils angeordnete Abstützung kann dabei ein geringeres Spiel aufweisen, da sie stets von Wasser umspült ist und etwaige Schmutzpartikel vom vorbeiströmenden Wasser wieder mitgerissen werden. Zudem ist die Neigung zu Kalkablagerungen deutlich geringer, da die Abstützung nicht trockenfallen kann. Wird die Abstützung in Form einer durchbrochenen Kunststoffscheibe ausgeführt, ist der erforderliche Aufwand zudem äußerst gering, so dass die genannten Vorteile annähernd kostenneutral realisiert werden können.This construction offers decisive advantages. So the desired remains Play between centering sleeve and the pin holding the valve actuator so that the smoothness the order is preserved. The game can also be chosen as large that contamination does not endanger the functionality of the valve. A Lime deposits that form the source of such contaminants if the tap is frequent is alternately dry and wet. Through the second tour you can Safe positioning of the sealing washer in front of the valve seat achieved become. The support arranged on the pressure side of the check valve can have less play because it is always washed by water and any dirt particles are carried away by the water flowing past become. In addition, the tendency to limescale is significantly lower, because the support cannot fall dry. The support is in the form of a perforated plastic disc executed the effort required is also extremely low, so that the above Approximate advantages can be realized cost-neutral.
